Extraction of Gold, Gold Extraction Process, Gold Ore

Gold mineral flotation normally adopts one stage grinding-flotation process, but stages grinding and flotation for ore with uneven distribution. Grinding fineness of gold. For the gold wrapped in sulfide minerals, sulfide ore reaches monomer dissociation; but for the gold with gangue, grinding fineness should reach gold monomer dissociation.
